Florid osseous dysplasia: report of a case presenting acute cellulitis

In this review, we examined a 45-year-old Asian man who had been diagnosed with florid osseous dysplasia (FOD) of the mandible and acute perimandibular cellulitis. This presentation occurred after a history of off-and-on swellings of the jaw and multiple treatments received at another hospital. An aggressive resection of the jaw was planned;however, the patient denied the treatment and came to our clinic to seek a second opinion. The patient was successfully treated by conservative surgery and antibiotic treatment with preservation of the jaw integrity and the mandibular neurovascular canal. Intraoperatively, a piece of a calcified mass was removed and submitted for histopathological examination. The specimen showed woven bone and densely sclerotic mass of calcified materials exhibiting reversal lines and inflammatory cell infiltration of the connective tissue. The definitive diagnosis was FOD with a secondary infection. Treatments for FOD were discussed

Intracranial extension of Schneiderian inverted papilloma: a case report and literature review

Inverted papilloma is an uncommon primary nasal tumor. Despite its benign nature, this tumor represents three typical characteristics: a high propensity of recurrence, local aggressiveness and association with malignancy. Inverted papilloma can reduce the patient’s quality of life due to compromised nasal function, extension to the orbit and brain. The authors reported the unusual case of a 72-year-old male patient with inverted papilloma, which fatally extended to the intracranial temporal fossa after multiple recurrences. To the authors’ knowledge, this is the twelfth case in the literature of inverted papilla extending into the temporal fossa. The current and pertinent literature in English, French and German was reviewed, and an algorithm for managing inverted papilloma was also proposed

An Association of Cryptococcus neoformans/ C. gattii Genotype and HIV Status in Asia: A Systematic Review

Objective: It has been known that VNI molecular type of Cryptococcus neoformans/C. gattii is strongly associated  with HIV patients. However, this paradigm has recently been challenged because of the high prevalence of VNI molecular type among non-HIV patients with cryptococcosis in East Asia. The purpose of this study was to answer the question: “Among cryptococcosis in Asia, is there an association between the genotype and the patient’s HIV status?” Methods: Using a systematic review and meta-analysis study design, we included all relevant published data, which were any type of study designs, mainly studied clinical Cryptococcus neoformans/C. gattii strains isolated in Asia and had available molecular typing data. The primary study variables were Cryptococcus neoformans molecular type (VNI/non-VNI or ST5/non-ST5) and the HIV status of the patients at the time of diagnosis. We used a randomeffects meta-analysis model to estimate the prevalence of HIV infection. Results: Sixteen retrospective descriptive studies during 2005 – 2018 (1,584 isolates) were included. Most of the cryptococcosis cases in East Asian countries were in non-HIV patients (72.4-81.8%), which differed from non-East Asian countries (2.6-28.3% associated with non-HIV patients). In East Asia, the HIV prevalence among VNI and ST5 infected patients ranged from 7.5% - 46.7% with the pooled prevalence of 19.8% (95% CI, 12.2% - 30.4%) and 5.3% - 52.4% with the pooled prevalence of 19.9% (95% CI, 6.9% - 45.3%), respectively. In non-East Asia, the HIV prevalence among VNI and ST5 infected patients ranged from 48.3% - 98.8% with the pooled prevalence of 81.9% (95% CI, 73.3% - 88.2%) and 52.3% - 88.0% with the pooled prevalence of 74.9% (95% CI, 40.7% - 92.8%), respectively. Statistical heterogeneity was high in both analyses with the I2 of 79-89% in all analyses. Conclusion: Our results confirmed the low prevalence of HIV prevalence among VNI and ST5 strains in East Asian countries. The emergence of high virulence genotype causing disease in non-HIV patient is highly unlikely, because the VNI and ST5 were associated with HIV patients in other Asian countries. It can be hypothesized that the low HIV prevalence among VNI and ST5 strains in East Asian is due to the high susceptibility to cryptococcosis of people living in this region. This requires further investigation

Endoscope-Assisted Submandibular Sialadenectomy: A Review of Outcomes, Complications, and Ethical Concerns

Objectives: To review outcomes and complications of endoscope-assisted submandibular sialadenectomy (EASS) and to analyze this innovative technique with regard to ethical issues. Methods: We used a systematic review study design to identify clinical studies on EASS, published in English, French, German, and Thai. The last electronic search was conducted in September 2009. We checked the bibliographies of the identified articles, relevant local journals, and congress abstracts. Publications were further assessed and assigned their respective levels of evidence. We also investigated reporting on human subject protection, conflicts of interest, funding support, and commercial relationships. Results: Five case series reporting a total of 28 patients met the inclusion criteria. There was no need of recourse to open surgery. All of the authors claimed satisfactory cosmetic results. Complications were uncommon. However, no controlled trial was available, and outcome measures varied between studies. Human subject protection and funding sources were mentioned in only 2 articles. Commercial relationships and conflicts of interest could not be identified. Conclusions: All of the reports favor outcomes of EASS. However, their level of evidence is low, and the superiority of this procedure over the conventional surgery remains unknown. The success of this procedure should not be overemphasized in information for consent and mislead surgeons to begin it without adequate training and elaborate environment. The lack of ethical documentation creates a high degree of suspicion of the studies
